Option
for the Intel® Itanium® 2 Processor
The Intel® Itanium® compilers feature optimized instruction scheduling
for the Itanium 2 processor.
More functional units and lower latencies reduce nops
and instruction group boundaries (also called "stop bits"). This reduction
in nops and stop bits allows more complete filling
of bundles, fewer nops resulting from resource
starvation. Consequently, more instructions are used effectively during
each cycle.
There are no new instructions for the Itanium 2 processor.
